technique on loss factor and Young�s modulus of lead-tin alloys by Peter Svensson and Milan Friesel"> The authors quantify the effects of many variables on the production of tone in organ pipes. Studied are metal alloys; metal thickness; metal casting techniques including cloth and sand; metal treatments such as scraping (and orientation of scrape relative to the metal sheet), hammering; cutting from various parts of a cast sheet; orientation of cut relative to the metal sheet; down surface vs. up surface; casting temperature. Also, analysis of pipe metal from the Scherer organ at Tangerm�nde. 63 pages softbound |
